Question 672810: PLEASE HELP I HAVE A QUIZ ON TUESDAY
Okay, so lately I've been having trouble in Algebra. We're doing slopes and graphing them, and I get the basics. It's the more complicated stuff I get confused on.
y = mx+b
1.) y = x^2 - 1
2.) y = 5/2x - 3
3.) 2y = 4x + 8
4.) y = 2x^2 - 6

If you could please explain how to tackle these problems and do them successfully, I'd be really happy!
Thanks!
